From Lines to Shapes: Geometric-Constrained Segmentation of X-Ray Collimators via Hough Transform
Benjamin El-Zein, Dominik Eckert, Andreas Fieselmann +4
Collimation in X-ray imaging restricts exposure to the region-of-interest (ROI) and minimizes the radiation dose applied to the patient. The detection of collimator shadows is an e…

A Realistic Collimated X-Ray Image Simulation Pipeline
Benjamin El-Zein, Dominik Eckert, Thomas Weber +4
Collimator detection remains a challenging task in X-ray systems with unreliable or non-available information about the detectors position relative to the source. This paper presen…
